cemented directly to the trim panels, or over non-
combustible backing to shim it out relative to the
finished wall surface. Be sure the height of the side
pieces is between 29" (740mm) and 33
¹⁄₄
" (845mm),
and that the thickness of backing, adhesive, and
stone combined is not more than 13/16" (20mm).

Tile. There are many tile options from which to
choose. Here is one method of determining a
satisfactory arrangement:
Finish Coat
Backer
Board or
Metal Lath

1. Draw the maximum and minimum fireplace
opening dimensions on a large sheet of card-
board.
2. Place it on the floor and experiment with laying
the tiles around the opening, varying within the
limits to determine the best arrangement.
3. Trace and cut out a silhouette of the insert. Lay it
over the tiles to show how the insert will cover the
tiles when it is installed.
4. On another large piece of cardboard, cut an
opening to represent the limits for combustible
material, and position that on top of the tile
layout. Keep in mind that while combustible
material must not be brought inside the combus-
tible limits, it is entirely permissible to extend
noncombustible facing materials beyond those
limits to achieve a particular decorative effect.
5. Despite the most careful planning and the latitude
provided by the maximum and minimum opening
dimensions, it still may be necessary to cut some
tiles to achieve a balanced appearance. Your tile
supplier or local tool rental outlet should be able
to supply the necessary equipment and explain
how to use it properly.
Consult your Vermont Castings dealer for advice and
suggestions for this process.

Use the Right Adhesives
The adhesive must be suitable to the chosen material
and have a temperature rating of at least 400
°
F
(204
°
C). High temperature silicone is an example.
Maintain a Safe Clearance to the Mantel
The clearance to the mantel and/or top trim must be at
least 43” (1090mm), measured from the finished hearth
surface. This clearance cannot be reduced by adding
shields.
